[oops] XFS? 2.6.3 build with gcc 3.3.3 running on Opteron

[Chris Meadors]

Just got this oops, looks like it might be XFS related.  But I'm no good
at decoding these things.

As the subject says this is a plain vanilla 2.6.3 kernel built with the
just released gcc 3.3.3.  All file systems are XFS.

Thanks.


Bad page state at prep_new_page

Trying to fix it up, but a reboot is needed
